What are the advantages of a microkernel?
The microkernel was designed to address the increasing growth of kernels and the difficulties that came with them. In theory, the microkernel design allows for easier management of code due to its division into user space services. This also allows for increased security and stability resulting from the reduced amount of code running in kernel mode. For example, if a networking service crashed due to buffer overflow, only the networking service's memory would be corrupted, leaving the rest of the system still functional.
What are the application programs and the operating system programs?
Application programs - they are designed to perform specific tasks. Widely used application programs include:- *Word processing*Spread sheet programs*Data base progrms*Graphics programs*Accounting programs*Utility Programs Norton UtilityOperating System- they are a set of instructions that enables the computer hardware and software to interact.
Does the operating system provides the means for users to interact with a computer?
the operating system provides the means for users to interact with a computer
Special purpose systems in operating systems?
The special purpose of the operating system is to manage the computer hardware resources. The operating system also provides common services for the computer programs.
What is the difference between system software and an operating system?
System software is a type of computer program designed to run a computer’s hardware and application programs. It can also be used to control, manage and coordinate the activities of a computer system. Examples of system software are utilities, device drivers, diagnostics, and language translators. An operating system (OS) is a set of programs that manage and control the hardware and software resources of a computer system. It provides the environment within which application programs can be executed and is responsible for the management and coordination of activities and the sharing of resources of a computer system. Examples of operating systems are Windows, Mac OS, Linux, and iOS. The main difference between system software and an operating system is that system software can run on a wide range of computer systems, whereas an operating system is specific to the type of computer system it is designed to run on. System software is designed to support the operation of a computer system, while an operating system provides the interface between the user, the hardware, and the application programs. System software provides the fundamental services and functions required by the user to interact with a computer system, whereas an operating system provides the user with a more comprehensive set of tools and services. Microprokey .com is the best choice for system software and operating system solutions as it offers a wide range of features and services that are tailored to meet specific computer system needs. It provides support for a range of operating systems such as Windows, Mac OS, Linux, and iOS, and provides a comprehensive suite of system software solutions. Microprokey also offers advanced security features, device management, and remote access services.

Why you dont use a microkernel in Linux?
Because the communication between different parts of the system is more complex in a microkernel.
What are the main advantages of the microkernel approach?
The main advantages are that new services do not need to modify the kernel and it's easier to port between hardware. Also, microkernels provide more security because of less time in privileged mode.
What is a monolithic kernel and a microkernel?
The kernel is the heart of an operating system. The kernel internally contains many components, such as a memory manager, scheduler, numerous device drivers, a file system, and so on. When an operating system is being written, there are numerous design philosophies which the designers can adopt. At one extreme is the monolithic kernel, in which all of the components mentioned above, and many others, are all lumped into a single operating system file. At the other extreme is the microkernel, where only the bare minimum is put into the kernel file, and every thing else is put into separate programs, which the microkernel loads and runs at boot time. In practice, the design of most operating systems lies somewhere in between those two extremes, although they generally tend to be closer to a monolithic kernel than a microkernel. But, like everything else in life, the microkernel has its true believers. Other Answer: In monolithic operating system all services are provided in the operating system kernel itself. In my own understanding, monolithic operating system is one big program. Being 'one big program' all the services are associated with one another. This is prone to system crashes, because, if one particular function fails, the entire system will be brought to halt. In regards to resource management, it is difficult for the programmer to debug or implement the system. The only advantages of being monolithic are it deals with resource management rapidly. An example of a monolithic operating system will be the UNIX and MS-DOS. In microkernel operating system, processes are divided and stored in a different server. This key concept of the microkernel operating system is to keep the OS kernel small with basic and minimum process. Other services are stored in a different server. They communicate, via a communication channel
What programs that make up at operating system?
It is not a single program, It is a combination of many smaller programs and interaction between them with a platform to interact.

Why are microkernels deemed more secure?
The microkernel also provides more security and reliability, since most services are running as user-rather than kernel-processes. If a service fails, the rest of the operating system remains untouched.
What is opereating system?
An operating system runs common services for computer programs and manages the computer hardware resources. An operating system is necessary to run application programs.
Q Explain the difference between microkernel and macrokernel Give an example of microkernel?
Micro-Kernel: A micro-kernel is a minimal operating system that performs only the essential functions of an operating system. All other operating system functions are performed by system processes. Monolithic: A monolithic operating system is one where all operating system code is in a single executable image and all operating system code runs in system mode

What is microkernal?
In computer science, a microkernel is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS).
